Randi entered the international spotlight in 1972 when he challenged the public claims of Uri Geller
Randi has worked as a professional stage magician and escapologist since 1946. In 1955, he broke Houdini's record for survival in a sealed coffin (1 hour, 33 minutes) by 11 minutes. In his early career, Randi was part of numerous stunts involving his escape from jail cells and safes.
In this short film, Randi exposes Uri Geller and Peter Popoff. He ends with a comedy review against many medical self-proclaimed spiritual healers.
